Bronchorrhea is the production of more than 100 mL per day of watery sputum.[1] Chronic bronchitis is a common cause, but it may also be caused by asthma,[2] pulmonary contusion,[3] bronchiectasis, tuberculosis, cancer, scorpion stings, severe hypothermia and poisoning by organophosphates and other poisons. Massive bronchorrhea may occur in either bronchioloalveolar carcinoma, or in metastatic cancer that is growing in a bronchioloalveolar pattern.[1][4][5] It commonly occurs in the setting of chest wall trauma, in which setting it can cause lobar atelectasis.[6]
